Quick Reference
Los Angeles County Local Rules
Specific requirements for Criminal Defense cases in Los Angeles Superior Court - Criminal Division
California Penal Code § 1054 and LASC Local Rules
Criminal discovery in LA County follows California Penal Code § 1054-1054.10, requiring prosecution disclosure of evidence favorable to the defense. LA Superior Court requires all exhibits be exchanged at least 10 court days before preliminary hearing per LASC Local Rule 4.30. The Criminal Courts Building downtown handles most felony matters, while 9 district courthouses handle misdemeanors regionally.
LASC Local Rule 4.30 - Pretrial Discovery
All exhibits must be exchanged at least 10 court days before preliminary hearing, with witness lists provided 5 days before trial. Felony cases require trial readiness conferences where exhibit lists are finalized. Late disclosure may result in exclusion of evidence per Evidence Code § 1054.5.
The 10-day rule is strictly enforced in LA County. Bring exhibit binders to all pretrial conferences. Judges routinely exclude late-disclosed exhibits, especially in high-profile cases. Digital exhibits must be provided on USB drive and uploaded to LA Court Connect.
Body-Worn Camera Footage Protocols
LAPD and LA County Sheriff body-worn camera footage is discoverable per AB 748 and must be disclosed within 45 days of a critical incident. Footage exceeding 25 MB must be split into segments for e-filing, or provided via secure file transfer with court approval.
BWC footage is central to many LA County cases. Request early through informal discovery or Pitchess motion. Redaction of bystander faces delays disclosure. Budget time for reviewing hours of footage and preparing transcript exhibits.
Gang Enhancement Evidence (Penal Code § 186.22)
Prosecution must disclose all gang expert evidence 30 days before trial, including expert's opinions, bases, and CalGang database entries. Defense may challenge gang evidence at pretrial hearing per People v. Sanchez requirements.
LA County prosecutes more gang cases than any jurisdiction in California. Expert testimony requires extensive foundational exhibits (gang indicia, territory maps, prior contacts). Prepare defense expert exhibits early to challenge shaky gang allegations.

Common Challenges in Los Angeles County
Late Brady Disclosure
File Penal Code § 1054.5 motion to compel and request continuance if late disclosure prejudices defense preparation. LA County judges grant continuances when prosecution violates discovery deadlines. Document all discovery violations for potential appeal issues.
Voluminous Body-Worn Camera Footage
Request specific incident times from prosecution to narrow footage review. Use video editing software to create clips of relevant segments with timestamps. File exhibits as video clips rather than entire multi-hour recordings. Consider hiring legal videographer for complex cases.
Multiple Courthouses and Divisions
Verify correct filing location - felonies generally go to downtown Criminal Courts Building, while misdemeanors are heard regionally. Each courthouse has different local customs. Consult with local defenders to learn judge-specific preferences and filing procedures.
Gang Expert Testimony Exhibit Requirements
Prepare comprehensive exhibit binder for gang expert including predicate offense evidence, territory maps, CalGang printouts, and expert CV. File Daubert/Kelly motion to exclude unreliable gang evidence and prepare defense gang expert exhibits to counter prosecution theory.

How to Prepare Criminal Defense Exhibits for Los Angeles County
Request Discovery from Prosecution
File informal discovery request and Penal Code § 1054.5 motion if necessary, requesting all Brady/Giglio material, police reports, witness statements, and scientific evidence.
Los Angeles County Note: LA County DA's office uses a discovery portal for most cases. Request access early and download all materials. For LAPD cases, separately request body-worn camera footage via AB 748 public records request.
Organize Evidence by Category
Separate exhibits into police reports, witness statements, forensic evidence, impeachment material, and defense evidence. Create exhibit list with People's vs Defense numbering.
Review and Redact Sensitive Information
Redact Social Security numbers, birthdates, home addresses, and confidential informant identities per Evidence Code § 352 and court protective orders.
Los Angeles County Note: LA County requires redaction certificates for any exhibits containing personal identifying information. File proposed redacted versions with the court 10 days before filing if redactions are contested.
Prepare Expert Exhibits
Work with forensic experts to create demonstrative exhibits, charts, and diagrams explaining scientific evidence. Ensure all expert materials comply with Kelly/Frye or Daubert standards.
Los Angeles County Note: LA County judges are sophisticated consumers of forensic evidence. Prepare high-quality visuals for fingerprint, DNA, or digital forensics testimony. Budget for professional exhibit preparation in serious felony cases.
Create Exhibit Binders
Assemble trial binders with tabs for each exhibit, including authentication foundation, chain of custody, and relevance arguments.
E-File Exhibit List
Upload exhibit list to LA Court Connect at least 10 court days before preliminary hearing and 5 days before trial, including descriptions and witness foundations.
Los Angeles County Note: LA County requires electronic exhibit lists in PDF format with hyperlinks to exhibits when possible. Bring backup USB drives to court as courtroom technology can be unreliable in older courthouses like Compton or Long Beach.
Pre-Mark Physical Exhibits
Apply exhibit stickers to physical evidence (drugs, weapons, clothing) before trial, coordinating numbering with prosecution to avoid conflicts.
